Transferring the design research value into guiding sustainable strategy creation and bridging design research and sustainable development practices is necessary. In the conversation, we proposed a design-based capacity-building approach as a mechanism to take this action. We presented the ECODeCK project as the ground to invite audiences and participants to exchange their stories and experiences regarding the contributions of design communities towards sustainable development actions. This will be carried out by mapping and integrating different design-based approaches to develop capacity-building practices for sustainability and circularity. Ultimately, we will reflect on how these approaches and practices could reframe design research and design education, aiming at extending the impact across academia, the environment, industry, government, and society.
